CAUTION!
①
. The power cord and the wire of the fresh air valve are high-voltage, while the communication cord
and connection wire of the wired controller are low-voltage. They should run separately against
electromagnetic interference.
②
. The high-voltage and low-voltage lines should pass through the rubber rings at different electric box
covers.
③
. Do not bundle the connection wire of the wired controller and the communication cord together, or
arrange them in parallel, otherwise improper operation would occur.
④
. The high-voltage and low-voltage lines should be fixed separately and securely, with internal big
clamps for the former and small clamps for the latter.
⑤
. Tighten the indoor/outdoor connection cord and power cord respectively on the terminal boards with
screws. Faulty connection may cause a fire.
⑥
. If the indoor unit connection cord (to the outdoor unit) and power supply are wired incorrectly, the air
conditioner may be damaged.
